Amlodipine Related Compound A

Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
Application
This pharmaceutical secondary standard can also be used as follows:

Development of a stability-indicating reverse-phase ultra-performance liquid chromatographic (RP-UPLC) method for determining related impurities of S(−)amlodipine and S(−)metoprolol succinate in their combined tablet dosage[1] Ultra-high pressure liquid chromatographic (UHPLC) separation and estimation of amlodipine and bisoprolol-related impurities in the combined pharmaceutical formulation of the parent APIs[2] Development and validation of a UHPLC method for quantifying impurities of valsartan, amlodipine besylate, and hydrochlorothiazide in their combined tablet dosage
Separation and determination of amlodipine and atorvastatin, along with their impurities using a stability-indicating RP-HPLC method in their combined solid dosage forms[3] General description
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

It is an impurity of the long-acting calcium channel blocker, amlodipine, that belongs to the class of 1,4-Dihydropyridine (DHP) calcium antagonists. The parent active pharmaceutical ingredient is used in the treatment of hypertension and anginal chest pain.[1] Other Notes
